The 100 Best Android Apps of 2015

TextSecure

FreeIf you're worried about the NSA or anyone else peeking at your text messages, consider TextSecure. Messages sent to other TextSecure users are encrypted over the air, but the app will also encrypt all of your text messages when they're at rest on your phone to keep them away from prying eyes. We first reviewed the app when it was in Beta, but it's since had a full version release and is ready for prime time.
